   Note: [Now mostly or quite disused.]
         [1913 Webster]

               Two crowns in my pocket, two pair of cards.
                                                  --Beau. & Fl.
         [1913 Webster]

   2. Two things of a kind, similar in form, suited to each

   6. Two members of opposite parties or opinion, as in a
      parliamentary body, who mutually agree not to vote on a
      given question (in order, for example, to allow the
      members to be absent during the vote without affecting the
      outcome of the vote), or on issues of a party nature
      during a specified time; as, there were two pairs on the
      final vote. [Parliamentary Cant]

   Note: A member who is thus paired with one who would have
         voted oppositely is said to be paired for or paired
         against a measure, depending on the member's position.
         [1913 Webster +PJC]

   7. (Kinematics) In a mechanism, two elements, or bodies,
      which are so applied to each other as to mutually
      constrain relative motion.
      [1913 Webster]

   Note: Pairs are named in accordance with the kind of motion
         they permit; thus, a journal and its bearing form a
         {turning pair}, a cylinder and its piston a {sliding
         pair}, a screw and its nut a {twisting pair}, etc. Any
         pair in which the constraining contact is along lines
         or at points only (as a cam and roller acting
         together), is designated a {higher pair}; any pair
         having constraining surfaces which fit each other (as a
         cylindrical pin and eye, a screw and its nut, etc.), is
         called a {lower pair}.
         [1913 Webster]

   {Pair royal} (pl. {Pairs Royal}) three things of a sort; --
      used especially of playing cards in some games, as
      cribbage; as three kings, three "eight spots" etc. Four of
      a kind are called a double pair royal. "Something in his
      face gave me as much pleasure as a pair royal of naturals
      in my own hand." --Goldsmith. "That great pair royal of
      adamantine sisters [the Fates]." --Quarles. [Written
      corruptly {parial} and {prial}.]
      [1913 Webster]

   Syn: {Pair}, {Flight}, {Set}.

   Usage: Originally, pair was not confined to two things, but
          was applied to any number of equal things (pares),
          that go together. Ben Jonson speaks of a pair (set) of
          chessmen; also, he and Lord Bacon speak of a pair
          (pack) of cards. A "pair of stairs" is still in
          popular use, as well as the later expression, "flight
          of stairs."
          [1913 Webster]
